I have a 2002 dbl cab 4x4 w/factory locker. The only voltage reading I'm getting from the connector behind the gas tank before the harness jumps down to the axle is from the center pin, the test light flashes consistently with the dash rear diff lock light.
The rest of the 4wd system works correctly.
When I purchased the truck the abs fuse was pulled and still is, assuming po didn't want to replace those sensors.
Would this effect the locker operation? I wouldn't think so.

Any ideas would be nice.
I do not really want to fork over $500.00 for manual cable conversion.

Anyone with a similar truck care to pull their abs fuse and see if their locker still engages....that is kind of random but you never know.

Thanks
